Coven Horror

This nightmarish large monstrosity is a result of multiple Witches or Hags who made pacts with a Demon but failed to complete their end of the agreement. Fused with the wailing bodies of children to remind the Coven Horror of its failure. Usually found in the Abyssal Realm but some have been known to make it back to the Material Plane.
